MCQ
Given below are some statements concerning formic acid, which of them is true
  • A
    It is a weaker acid than acetic acid
  • ✓
    It is a reducing agent
  • C
    When its calcium salt is heated, it forms a ketone
  • D
    It is an oxidising agent
✓

Answer

Correct option: B.
It is a reducing agent
b
If a compound gets oxidized (as formic acid can), then another compound has to be reduced. The compound that gets oxidized is called a reducing agent. It reduces Tollen's reagent to silver mirror.

Formic acid acts as a reducing agent as it can reduce Tollen's reagent, Fehling solution, mercuric chloride and $KMnO _4$ etc.
